Agilent/Keysight AC6912H

The Keysight AC6912H is a 12 kVA three-phase AC power source engineered for high-demand testing in avionics, power electronics, and industrial systems. It delivers precise AC, DC, or combined AC+DC output across configurable single, two, and three-wire topologies. With maximum AC voltage of 320 Vrms, DC voltage to 452 V, and frequency capability to 5 kHz, the AC6912H supports both steady-state and transient verification.

The instrument incorporates a built-in harmonic analyzer, custom waveform generation, and power line disturbance simulation - critical for pre-compliance validation. A 5-inch color LCD display and programmable output sequencing enable flexible test automation. LAN (LXI core) and USB connectivity, with optional GPIB and analog/digital I/O modules, integrate into existing test architectures.

Multiple protection schemes - overvoltage, overcurrent, overpower, and overtemperature - safeguard connected devices. Two input configurations support 380–480 V or 180–235 V mains.
